Product Description

This looks like the receiver I need, but how do I know if it's the right one?

1. Frequency: Check the back of your remote or receiver in this case, to make sure the
frequency is 300mhz (megahertz).

2. Dip Switches: Open the battery compartment on your old garage
door remote and look to see how many dip switches (tiny switches in a row)
it has. If your old remote had 10 dip switches, then it's a match for this
remote. If you don't have your old garage door remote, you can also look
to see how many dip switches are on the back of your garage door opener
(the overhead unit in your garage). The number of dip switches on the back
of the opener is the same as on the remote.
